At some point we have to come to this realization in the west that absolutism is never the answer. Free speech is good upto certain extent, the way it was at Twitter before the rich and powerful took over. Moreover, it is content moderation and it doesn't have anything to do with free speech.
That's the norm in Elon Musk's Twitter. Since his takeover, content like white supremacy, antisemitism, and industrial state-level propaganda operations from fascist and totalitarian regimes is perfectly ok to publish on that platform. Criticism of Elon Musk or fascist regimes, however, is completely different.
Elon Musk's Twitter was also caught hardcoding censorship and throttling of both pro-Ukraine discussions and users who published pro-Ukraine content. Russian bots however have free reign.
More importantly, Elon Musk's Twitter is finding itself in trouble in Brasil not because of censorship, but because Elon Musk made it his point to go to great extents to avoid even appointing a legal representative to handle complains of illegal activity. This isn't even about censorship, but complying with basic legal requirements. It's like bitching that having to pay taxes is persecuting based on free speech just because you refuse to even file a form.
